Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Why GPL-2.0-only? Isn't this based on other code which is either
dual-licensed or BSD license?

Your board needs clock frequency.

Usual comment: this (entire clock or at least its frequency) is usually
not a property of a SoC, but board. Did something change here in SA8775?

Missing space after :

This does not match your bindings, so nothing here was tested against
your own files which you sent.

Compatible goes first, then reg, then ranges.

Why this one is outside of soc node? Or are we inside soc? But then
ARMv8 timer cannot be here... dtbs W=1 would warn you, wouldn't it?
